The largest living organism on Earth "Pando" is a colony of aspen-shaped poplar (USA, Utah). Scientists have determined that 47 thousand stems come from a single once living poplar. All 47 thousand stems have a single root system, and can be called a single organism, which weighs 6 thousand tons. Pando is 80 thousand years old, which makes it one of the main candidates for the title of the longest-living organism on the planet. 2.7K views03:22
